Problems solved by technology

However, due to the constant installation position of each sensor and the different sampling rates among them, the existing positioning methods will detect errors when the bumpy road surface, or the vehicle body fluctuates too much, or the machine rotates, collides, etc. As a result, the accuracy and robustness of mapping and positioning algorithms are reduced, which in turn affects map quality and positioning accuracy
[0003] E.g figure 1 As shown in Fig. 1, it shows the impact of the tilt of the robot body on the two-dimensional plane lidar detection data. When the body is tilted, the measured obstacle data will be wrong, which will reduce the accuracy and robustness of the mapping and positioning algorithms. This will affect the map quality and positioning accuracy

Abstract

The invention provides a robotic map-building and positioning system and a robot. The robotic map-building and positioning system comprises: an obstacle detection module for acquiring information of obstacles around a robot; an inertial measuring module for acquiring acceleration and angular velocity data of the robot; a correcting module for correcting measured information of the obstacles; a map-building and positioning module for building an E-amp for an environment where the robot locates according to the information of the obstacles around the robot, and acquiring current attitude of therobot. The robotic map-building and positioning system and the robot have the advantages that the measured information of the obstacles around the robot can be corrected, the information of the obstacles is more reliable, a map-building and positioning algorithm is more accurate and robust, and map quality and robot positioning precision are improved accordingly.

Description

technical field [0001] The invention relates to the technical field of robot navigation and positioning, in particular to a robot mapping and positioning system and a robot. Background technique [0002] Existing mobile robots usually use sensors installed on the robot body to scan the surrounding environment, use these sensors to measure the position information of obstacles around the robot, and record the mileage information of the robot itself. A map of the robot's environment and the robot's location information. Commonly used sensors include two-dimensional lidar, depth cameras, infrared ranging, ultrasonic ranging, collision sensors, encoders, etc. However, due to the constant installation position of each sensor and the different sampling rates between each other, the existing positioning methods will detect errors when the road is bumpy, or the vehicle body undulates and vibrates too much, or the machine rotates, collides, etc. Therefore, the accuracy and robustne...
